[PATCH, rs6000] Fix compilation issue on power7 from r235577

- Subject: [PATCH, rs6000] Fix compilation issue on power7 from r235577
- Authentication-results: sourceware.org; auth=none
This patch changes some of the dejagnu options to better restrict
where the test cases run so that they will no longer cause failures on
power7 machines.
Based on a subsequent patch I also updated the code formatting (indentation,
etc.) for the code from the original patch (r235577) in both the test cases
and in rs6000-c.c.
Bootstrapped and tested on powerpc64le-unknown-linux-gnu (on both
power7 and power8) and powerpc64-unknown-linux-gnu (power8) with no
regressions. Is this ok for trunk?
